Ah, you didn't say that.
In that case, you probably need to bind `n' and `p' in `image-mode-map'. You
just need commands that visit the next/previous file in sequence, then bind `n'
and `p' to them. Shouldn't be hard. Iterate over `directory-files' (e.g.
filtered by `image-file-name-regexp'), and call `find-file'.
Might be a reasonable addition to the default `image-mode-map' bindings. After
you create the commands, think about submitting such bindings as an enhancement
via `M-x send-emacs-bug-report'.
Something like this, perhaps (you can improve it, certainly):
(require 'image-mode)
(define-key image-mode-map "n" 'next-image)
(define-key image-mode-map "p" 'previous-image)
(defun next-image (arg)
"..."
(interactive "P")
(unless (and (buffer-file-name) (eq major-mode 'image-mode))
(error "Not visiting a file in image mode"))
(let* ((regexp (image-file-name-regexp))
(files (directory-files default-directory nil regexp))
(len (length files))
(this (file-name-nondirectory (buffer-file-name)))
(idx 0))
(catch 'next-image
(dolist (file files)
(when (string= this file) (throw 'next-image (1+ idx)))
(setq idx (1+ idx))))
(setq idx (+ idx (if arg -1 1)))
(when (< idx 0) (setq idx (1- len)))
(when (>= idx len) (setq idx 0))
(find-file (elt files idx))))
(defun previous-image (arg)
"..."
(interactive "P")
(next-image t))

image-dired-thumb-size, `image-dired-thumb-width', and
`image-dired-thumb-height' should let you control the size.
